Hand hygiene compliance in the intensive care units of a tertiary care hospital

Abstract

Context: Hand hygiene (HH) is the most important measure to prevent hospital-acquired infections but the compliance is still low. Aims: To assess the compliance, identify factors influencing compliance and to study the knowledge, attitude and perceptions associated with HH among health care workers (HCW). Settings and Design: Cross-sectional study conducted in 42 bedded Medical (Pulmonary, Medicine and Stroke) intensive care units (ICU) of a tertiary care hospital. Materials and Methods: HCWs (doctors and nurses) were observed during routine patient care by observers posted in each ICU and their HH compliance was noted. Thereafter, questionnaire regarding knowledge, perception and attitudes toward HH was filled by each HCW. Statistical Analysis: Percentages and χ² test. Results: The overall compliance was 43.2% (394/911 opportunities). It was 68.9% (31/45) in the intensivists, 56.3% (18/32) in attending physicians, 40.0% (28/70) in the postgraduate residents and 41.3% (301/728) in the nurses. Compliance was inversely related to activity index. Compliance for high, medium and low risk of cross-transmission was 38.8% (67/170), 43.8% (175/401) and 44.7% (152/340), respectively. Conclusions: Compliance of the study group is affected by the activity index (number of opportunities they come across per hour) and professional status. The HCWs listed less knowledge, lack of motivation, increased workload as some of the factors influencing HH.
